Key Biscayne, FL (Sports Network) - Two-time champion Victoria Azarenka pulled out of the Sony Open tennis event on Friday, citing a right ankle injury.
The 23-year-old star was also forced to pull out of a quarterfinal at the big WTA event in Indian Wells last week because of the injury.
The former world No. 1 and reigning Australian Open champion Azarenka was scheduled to meet American wild card Madison Keys in a second-round match on Day 4 in Florida, but the second-seeded Belarusian was replaced in the draw by American lucky loser Lauren Davis.
Azarenka was the Miami champion in 2009 and 2011.
